The diagram gives information about the stages involved in the recycling of plastic bottles.
Overall, this mainly mechanical process consists of nine stages, where used plastic bottles are turned into pellets, then raw materials, and finally, into various new products.
The recycling starts with bottles being disposed of into special garbage bins. Next, lorries take them to the recycling facility, where workers will sort them into usable and non-usable. The sorted bottles are then compressed into blocks.
It is in the fifth stage where the bottles lose their shape altogether after being crushed into small pieces. Afterwards, these pieces are washed and turned into ball-shaped tiny items known as pellets. The next step involves the pellets being exposed to heat in order to form necessary raw material. In the final stage, that material will be used to manufacture a variety of products, ranging from clothes and bags to pencils and plastic containers.
